Some try to pass chemtrails off as nothing more sinister than contrails. But even casual inspection and comparison of the two shows that they are not the same at all. Contrails, usually occur at high altitudes & quickly dissipitate. Chemtrails on the other hand, stay in the sky and continue to spread out. A few chemtrails can turn a formerly blue skies,sunny day into a gray overcast day as the chemtrails do not disperse, they just keep spreading and stay there. Also chemtrails are many times laid at much lower altitudes than contrails. Another difference is that a plane laying contrails actually appears to be going somewhere, to a destination. Chemtrail spray planes frequently lay trails in patterns with loops and x's following a flight plan that no ordinary plane with a destination would follow.Copyright image courtesy of Holmestead.ca
